Effect of Posttreatment on the Catalytic Performances of Fe-N-C for Oxygen Reduction Reactions

Herein, we report the significance of posttreatment in the design of high-performance Fe-N-C-type catalysts for oxygen reduction reaction (ORR). Enhancing the catalytic performance of Fe-N-C requires a postprocess for removing the aggregated iron species formed during high-temperature pyrolysis sinc...
